Multiserver on top of MySQL-Cluster

I think about to setup a new multiserver setup.
Therefore I'ld like to know if it's possible in terms of wise to setup a multiserver enviroment on top of a Galera MYSQL Cluster. dbispconfig should run as an intance on this cluster, Client DB also. Concerns regard replication.
HW base is a 3 server cluster.

I am running my multi-server environment on a galera cluster without any problems. I have 3 web/db servers in a single galera cluster. I then have a standalone server that I use for managing these servers. The most important thing to do when adding slaves to the master is to use unique db names and users. You will cause serious problems if you don't do this initially.

I don't see there being any issues including the master server in the database cluster if thats what you're looking to do.
